One time my cousin and I taped a black velvet canister to the side of his car and pulled up in front of a teen party we had been invited to and just sat there for a few minutes and then a bunch of teenagers started jumping over the back fence with their 6 packs.
Later we pulled some guy over for speeding and then laughed at him and later the cops caught up with us and they would have charged us with impersonating officers but for some reason they just thought it was funny and told us not to do that any more.
I recall this one party in High School. The tap for the keg wasn't working so these guys started bashing the keg on the pool coping. They finally got a hole in it and raised the keg over their heads to drink out of it.
About a half hour later the cops came and everyone rushed the fence and knocked it down.
